The aircraft damaged the approach and field lights, disabling the airport approach lighting system. Airport Rescue and Fire-Fighting (ARFF) responded and the occupants of the aircraft were reported to be uninjured. The extent of damage to the aircraft is unknown and there was no reported fire. The Transportation Safety Board has been advised. All runways were closed to traffic from 18:50Z to 19:50Z and, at time of reporting, Runways 11/29 and 02/20 remain closed by NOTAM with 16/34 remaining as the active runway. The instrument landing system on Runway 16 was functional but the airport did not have approach lights so, the airport could only provide daylight operations. At 21:41Z, NAV CANADA confirmed that the runway lighting system for Runway 16/34 was repaired; operations at St. John's were no longer restricted to daylight hours. Runways 02/20 and 11/29 remained closed, per NOTAM, and would remain closed until the disabled aircraft could be removed.
UPDATE According to the TSB Final Report A12A0082 authorized for release on 18 December 2013: On 13 August 2012, a Volga-Dnepr Airlines Ilyushin IL-76TD-90VD aircraft (registration RA-76511, serial number 94-08), operating as flight VDA4118, departed Prestwick, Scotland, for St. John's International Airport, Newfoundland and Labrador, on a scheduled cargo flight with 10 crew members on board. An instrument landing system approach was carried out, and at 1612 Newfoundland Daylight Time, the aircraft touched down on Runway 11. Following touchdown, the crew was unable to stop the aircraft before it reached the end of the runway. The aircraft came to rest in the grass, the nose wheel approximately 640 feet beyond the end of the pavement. There were no injuries, and aircraft damage was limited to cuts and localized rubber melting on the main tires. The accident occurred in daylight hours. The runway overrun did not cause the emergency locator transmitter to activate. The occurrence aircraft landed with a tail wind that exceeded the aircraft manufacturer?s limitations. The combination of the tail wind and the fact that power levers were not reduced to idle until the aircraft was about 2000 feet beyond the threshold resulted in the aircraft landing approximately 4220 feet from the threshold, which reduced the available runway length to stop.
UPDATE TSB:A12A0082: The Ilyushin IL-76TD-90VD cargo airplane (RA76511) was landing on Runway 11 at St. John's airport and could not stop within the runway length. The airplane overran the runway and came to rest in the grass overrun area. There was minor damage to the aircraft and there were no injuries to the crew of 9.
